Ok I think I know what you mean.
you want maybe a line showing values, and in the same graph have staples showing the frequency of the values, right?
If you promise not to laugh, I´ll tell you what I did. (there´s probably a much better way to do this, but I couldn´t find it.)
I use two graphs on top of each other, the bottom one being a copy of the other, but with different field selected and a different display of data. The top one is set to see through.
I´m sure you´ve thought about this solution, and it´s not a very pretty one, but it works ok for me.
Fuga.
Ja, det är mycket kallt i Sverige.
